UTH only warm the ground above them, they do not warm the air. What you say above is true for well insulated enclosures, like PVC tanks, such as Boaphile, AP, etc. In a glass tank with a screen top, this is less of the case. However, most PVC enclosures, when the room temp is well below what the average temp in the tank needs to be, or even the cool side, will use a Radiant Heat Panel (RHP) to heat both the hot spot/hot side and the air in the enclosure.

You probably want a Ceramic Heat Emitter (CHE) to both warm the middle of the tanks both air and ground. In this instance, you will almost definitely not need a second UTH. I would consider a CHE for the hot side/middle area. You need to run that off a thermostat as well IMO, although some people use a dimmer and/or a low wattage CHE. I say get a good thermostat now that can run two devices because down the road you will need that anyway when you upgrade your BP's tank, hopefully to something more suited to a BP that keeps heat and humidity in better.
